Ukuminyana kwe-warp ne-weft yendwangu ye-fiberglass inquma ukusebenza kwendwangu ye-PTFE yezinga eliphezulu lokushisa. Ukuminyana okuphezulu kukhulisa amandla okudonsa kanye nokushelela kwendawo kodwa kunciphisa amandla okudabuka (ijika le-U elihlanekezelwe), ukuguquguquka, kanye nokungena okunamathelayo. Ukuminyana okuphezulu kulinganisa ukungena, ukumelana nokukhala, ukuguquguquka, nokuqedwa kwendawo. Ukuminyana okuphansi kufanelana nokugoba okuguquguqukayo; high density for non-stick kanye ukwahlukanisa.

I-Calender – ukucindezela indwangu eboshwe nge-PTFE phakathi kwamarola esibuko ashisisayo ku-360-380°C – kushintsha ngokuphawulekayo ukumila kwendawo, ukukhulula izakhiwo, ukungaboli, nokusebenza komshini. Yehlisa ukuhwaqaza ukusuka ku-Ra 0.5-1.0 μm kuya ku-<0.05 μm, ivala amaphinifa, ithuthukise ukumelana nokugqoka, kodwa inciphisa amandla okudabula nokuguquguquka. Ibalulekile ekukhululeni ama-liner kanye nokufakwa kukagesi.

Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu nendwangu ye-silicone kokubili kusebenzisa indwangu ye-fiberglass njengesisekelo kodwa ihlukile ezintweni zokumboza (i-PTFE resin vs irabha ye-silicone). I-PTFE iphumelela kakhulu ekungabambeni, ukumelana nokugqoka, kanye nokumelana namakhemikhali kufika ku-260°C. Indwangu ye-Silicone inikeza ukuguquguquka okuphakeme, ukufakwa kukagesi, nokumelana nomlilo (kufika ku-230°C). Khetha ngokusekelwe kokubalulekile kwakho.

Indwangu yokushisa ephezulu ye-PTFE (i-PTFE membrane material) iyinketho ephambili yezakhiwo eziqinile. Izinzuzo eziyinhloko: iminyaka engu-30+ yokuphila kwangaphandle, indawo ezihlanzekile (amanzi emvula ageza ukungcola), ukudlulisa ukukhanya okuthambile (6-13%), isilinganiso somlilo Sekilasi A, namandla afana nensimbi angaphansi kuka-1.5 kg/m². Isetshenziswa ezinkundleni zemidlalo, ezikhumulweni zezindiza, namabhilidi ayisakhiwo sodumo emhlabeni jikelele.

Indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza ukumelana kwamakhemikhali okukhethekile, imelana nama-asidi aqinile, ama-alkali, izinyibilikisi eziphilayo, namagesi abolayo. Lesi sihloko sichaza ngezinto ezimelana nayo, imikhawulo (izinsimbi ze-alkali ezincibilikisiwe, ama-ejenti anamandla e-fluorinating), nezici ezibalulekile ezifana nezinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.

Ukufakwa kwe-PTFE akukhawulelwe kundwangu ye-fiberglass. Lesi sihloko sethula ama-substrates angu-7 ahlukile - i-aramid, i-carbon fibre, i-PBI, insimbi enezimbotshana, i-graphite, i-asbestos (ikhishiwe), kanye nezigcwalisi ze-ceramic - nezici zazo zenqubo, izinzuzo, imikhawulo, nezinhlelo zokusebenza ezibalulekile.

Lesi sihloko sichaza ukuthi kungani indwangu ye-fiberglass engena-alkali iyisisekelo esincanyelwayo sendwangu ye-PTFE enezinga lokushisa eliphezulu. Ihlanganisa ukubopha kwamakhemikhali ngama-ejenti ahlanganisayo we-silane kanye nezakhiwo ezibalulekile zomzimba njengokuzinza kwe-thermal, ukuzinza kwe-dimensional, nokumelana nokugqwala - iqinisekisa ukusebenza okuhlala isikhathi eside ezindaweni ezinokhahlo.
